The 2023 Boston Pops Fireworks Spectacular, under the direction of Keith Lockhart, showcases an impressive lineup of guest artists, including award-winning R&B/soul group En Vogue (featuring current members Grammy-nominated Cindy Herron, Terry Ellis and Rhona Bennett) as headliners. Also taking the Esplanade stage are Broadway star Mandy Gonzalez (In the Heights), country duo LOCASH (Preston Brust and Chris Lucas), and three cast members from the Pops’ recent concert presentation of “Ragtime: The Symphonic Concert” (Alton Fitzgerald White, Elizabeth Stanley, and Andrea Jones-Sojola—all Broadway talents). The program includes several selections with the U.S. Army Field Band and Soldiers’ Chorus, who also lead the traditional patriotic sing-along, which includes John Philip Sousa’s “The Stars and Stripes Forever.”
